本文描述一种新近发展的30毫米硒砷碲摄象管。此管(BC4398)惰性降低,有较高的分辨率,并且由于扫描角减小而提高了配准性能。穿过面板的一根引线保证了非常低的并联电容耦合。此外,管子已在管内设置偏置光。以上各种特点使这种摄象管对于电视制作摄象机和包括高质量的广播电视摄象机在内的其它用途来说是有用的。 This article describes a newly developed 30 mm selenium arsenic telluride tube. This tube (BC4398) is less inert, has a higher resolution, and improves the registration performance due to the reduced scan angle. A lead across the panel ensures very low parallel capacitance coupling. In addition, the tube has been set in the tube bias light. These various features make the camera tube useful for television production cameras and other uses, including high-quality broadcast television cameras.
